I have framework experience with Laravel, Symfony, CodeIgniter, and Vue. Always up for a challenge, whether it's new development or tracking down a bug.

Freelance XML Developer - Willem Van Onsem

Developer by day, programmer by night. I obtained a master of science in civil engineering (computer science) and participated - together with several teams - in programming contests and hackathlons. I answer questions on StackOverflow on a daily basis and wrote courses on Artificial Intelligence and Digital Electronics. I am mainly interested in Haskell, Python, and Prolog. I worked as a researcher in the field of hyperheuristics (artificial intelligence), a teaching assistant in computer science and as a data scientist and technical lead developer in an AI startup. During my spare time I developed small (and larger) projects to help with daily routine. For me, a computer should aim to automate everything that is boring, such that one can pay more attention to what is interesting in life. After each session, I aim to write a document (usually within one week) that describes what we discussed. The public GPG key can be found here: https://pgp.mit.edu/pks/lookup?op=vindex&search=0x6A148004A6024E2B Usually available between 17:30 - 21:30 UTC (Monday to Friday) and 9:30 - 21:30 UTC (weekend). See for time conversions https://goo.gl/eWdDCG (week days) and https://goo.gl/kdvMsa (weekends).
